Lots of uninstalls not monitored. What version to use?

I have been using the latest beta since first released last year, but lately many Uninstall attempts “end with errors!” meaning I have to resort to Add/Remove Programs CP to do uninstalls. I assume these errors owe to the missing online “DB Monitored” feature, but given they’ve apparently abandoned development, I’m thinking I should just revert to an older (stable version) of the software.

Which would that be, 1.3 or even 1.2?
